The project proposes a public bathhouse integrated with a water cistern in Saigon city, Vietnam. Hidden in front of the historic Independence Palace, the project retraces the Vietnamese history and lifestyle to introduce a spatial void that celebrates critical silence and contemplation values, with a hope that many souls can healed, and social interactions can be elevated without the impact from urbanization. By constructing the project from the ground below, urban flooding and urban landscapes are addressed and transformed through a speculative form of architectural tree typology.
